Graphics Symbols By Name

QUESTION: I love your
cgSymCat program and the forty some
graphics symbols I can use on my graphics plots. But, I can never remember
which index number refers to which symbol. Can't I just ask for a plotting
symbol by giving a symbol name?

ANSWER: Yes, now you can. A recent update to the Coyote
Graphics routine cgSymCat allows you to ask
for a plotting symbol by name. To obtain a list of symbol names, type this.

IDL> Print, Transpose(cgSymCat(/Names))

All the Coyote Graphics routines
have been updated so you can use symbol names with the normal PSym keyword.
(See the figure below.)

IDL> cgPlot, cgDemoData(1), PSym='star', SymSize=2.0

Symbol names can be used with PSYM keywords.

It is even possible to connect symbols by using a minus sign in the symbol
name.
